 'operator' : result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?)
 
-The result of 32-bit shift was implicitly converted to 64-bits, and the compiler suspects that a 64-bit shift was intended.  To resolve this warning, either use 64-bit shift, or explicitly cast the shift result to 64-bit.
+The result of 32-bit shift was converted to 64-bits, and the compiler suspects that a 64-bit shift was intended.  To resolve this warning, either use 64-bit shift, or explicitly cast the shift result to 32-bit to make the intention clear.
